Key Areas : Cardiovascular disease, diabetes, heart failure, sepsis
Clinical Implications
Early Detection and Prevention : Monitoring microvascular function helps identify patients at high risk, enabling early intervention and preventive measures.
Disease Progression and Treatment Monitoring : Microvascular assessment provides a window into disease activity, aiding in the evaluation of treatment effectiveness.
Goal-Directed Therapy : Insights into microvascular health support goal-directed therapies, optimizing treatment plans tailored to individual needs.

Research Plan and Methodology
CapriS, Capillary Dysfunction in Sepsis
Population: 60 patients, >18 yrs with confirmed/suspected infection at ICU/IMCU <12hrs and SBP <90mmHg despite 10 mL/kg cristalloid.
Intevention: Laser speckle contrast imaging, with iontophoresis. Biomarkers. Echocardiography at set intervals.
Comparison: 30 healthy controls.
Outcomes: Primary outcome: peak capillary blood cell velocity (pCVB, mm/s). Secondary outcomes: Severity of condition, macrocirculatory parameters, biomarkers.
Research Plan and Methodology
MIND, Microangiopathy in Diabetes
Population: Patients with DM1 at diabetes outpatient clinic at Danderyd Hospital. Pilot: 20 healthy controls. Phase 1: 50 patients with severe DM1 complications and 50 healthy controls. Phase 2: 100 patients with no microangiopathy, 100 patients with mild microangiopathy, 50 with moderate microangiopathy, as classified by microangiopathy score [1] . Intervention: LSCI, blood tests and charts. Controls: Healthy controls in each cohort. Outcomes: Thermal regulation, flow regulation [1]: 10.1177/1479164120928303
Research Plan and Methodology
SCAPIS2Spectrum, Microcirculation Substudy
Population: Substudy to SCAPIS2. 900 in total to be included in 5 arms; O-CAD, ANOCA, HFpEF, HFrEF and diabetes, including corresponding controls from SCAPIS2 cohort. Intervention: LSCI, biomarkers, and adenosine stress cardiac MRI. Comparison: Healthy controls Outcome: Primary outcomes: Flowmotion analysis, post-occlusion hyperemeia, thermal provocations. Secondary outcomes: Biomarkers
